I'm going with my experience with online playKrantos said:To be honest, I don't know personally. I have friends who are borderline PS3 fan-boys, but they still hate PSN and prefer XBL. I've never tried it, so i was just basing my argument on their feedback.
Perhaps they've just had bad experiences, or maybe you've been lucky. IDK.
I've had the Xbox lag and crash on multiple occasions
the computer is flawless
the Wii is practicably unplayable minus Conduit (but I think Wii users aren't USED to what online should be like *looks at computer*)
the PS3 was NEARLY flawless (it lagged a bit when people left and joined but that was IT)
